ABSTRACT:
A method and apparatus for improving the control of prosthetic limb rotation in amputees in which a permanent magnet is implanted into the distal end of a residual bone and the bone rotation is sensed from movement of the magnetic field of the magnet and used to effect corresponding rotation of the prosthetic limb.
